Unplug the iPod USB Power Adapter if any of the following conditions exist: Â The power cord or plug has become frayed or damaged. Â The adapter is exposed to rain, liquids, or excessive moisture. Â The adapter case has become damaged. Â You suspect the adapter needs service or repair. Â You want to clean the adapter. Avoiding hearing damage Permanent hearing loss may occur if earbuds or headphones are used at high volume. Set the volume to a safe level. You can adapt over time to a higher volume of sound that may sound normal but can be damaging to your hearing. If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked. The louder the volume, the less time is required before your hearing could be affected. Hearing experts suggest that to protect your hearing: Â Limit the amount of time you use earbuds or headphones at high volume. Â Avoid turning up the volume to block out noisy surroundings. Â Turn the volume down if you can't hear people speaking near you. For information about how to set a maximum volume limit on iPod, see "Setting the Maximum Volume Limit" on page 29. Using headphones safely Use of headphones while operating a vehicle is not recommended and is illegal in some areas. Be careful and attentive while driving. Stop using iPod if you find it disruptive or distracting while operating any type of vehicle or performing any other activity that requires your full attention.

Discontinue use and consult a physician if you experience: convulsion, eye or muscle twitching, loss of awareness, involuntary movements, or disorientation.
